Masashi discovers a cute creature which resembles a jellyfish and names it Kurage-Bo. He secretly takes Kurage-Bo with him to school - for he fears that his mother will discover it if he were to leave it at home. But when Masashi attends his first class... much to his surprise - ALL the kids have pet creatures of their own. The ONLY thing that puzzles Masashi is that the children have special devices that can control them and they're having the creatures fighting one another.
